How to Perform Fraction Operations
Add / Subtract: Find the LCD, convert both fractions, then add or subtract the numerators. Example: 1/2 + 1/3 → LCD = 6 → 3/6 + 2/6 = 5/6.
Multiply: Multiply numerator × numerator and denominator × denominator, then simplify the result. Example: 2/3 × 3/4 = 6/12 = 1/2.
Divide: Flip the second fraction (reciprocal) and multiply. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6. Use the fraction simplifier to reduce the result to lowest terms.
